SIMULATION OF PROCEED® SURGICAL MESH APPLIED TO VENTRAL HERNIA REPAIR

Abstrakt

In the present research, Proceed® implant is considered. The system is subjected to short-time dynamic pressure load, similar to post-operative cough naturally occurring in human abdomen. The model refers to a clinical case of 5cm of hernia operated by Proceed implant fixed by 15 joints every 3cm around the orifice. The simulations of the implanted mesh are performed by means of the Finite Element Method. The implant is modelled as a membrane structure supported by visco-elastic springs. Elastic foundation representing the abdominal wall are also included. The finite element simulations are compared with the experiments performed on the physical models of hernia prepared with the use of porcine abdominal tissues, which supports the implant membrane. In the study the maximum value of the pressure equal to 43,34 kPa has been applied in the experiment and simulation. The appropriate Rayleigh damping parameters were included in the model. The good accordance of calculated and experimental results assures the model accuracy. The forces in joints can be calculated and compared with the tissue-implant joints strength and thus to estimate the hernia repair persistence. The proposed model and its finite element implementation and simulation can be applied drawing hints in planning the surgery with the use of Proceed implant.
